Abstract

The aim of this study was to investigate the concordance between COBAS Taqman 48 (Roche Molecular Systems, Pleasanton, CA, USA) and VERSANT HCV RNA 3.0 (Bayer Diagnostics, Terrytown, NY) test systems for the detection of hepatitis C virus (HCV) load. Plasma samples taken from 42 patients with chronic HCV infection between 15 May-15 June 2006, were included to the study, and HCV-RNA levels have been searched with the use of the two above mentioned systems. Thirteen of the samples (30.9%) yielded negative and 26 (61.9%) samples yielded positive results by both of the systems. Two samples that were found negative by COBAS system, displayed 3.38 and 3.41 log10 lU/ml HCV-RNA by VERSANT system, respectively, while one sample that was found negative by VERSANT system, displayed 2.52 log10 lU/ml HCV-RNA by COBAS system. The correlation and linearity of the tests were found high according to Pearson correlation analysis [(r= 0.904, p< 0.0005), (R2= 0.817)]. The viral load values detected by COBAS AmpliPrep/COBAS Taqman 48, were higher than the values obtained by VERSANT HCV-RNA 3.0, with a mean of 0.33 log10 Ill/ml. In conclusion, both of the systems yielded similar results, however, since HCV viral load values may differ in different systems, the follow-up of viral load should be done by the same system for a particular patient.

Özet

Bu çalışmada hepatit C virus (HCV) yükünün belirlenmesinde COBAS Taqman 48 (Roche Molecular Systems, ABD) ve VERSANT HCV-RNA 3.0 (Bayer Diagnostics, NY) test sistemlerinin uyumluluğunun araştırılması amaçlanmıştır. 15 Mayış-15 Haziran 2006 tarihleri arasında gerçekleştirilen çalışmaya kronik HCV enfeksiyonu olan toplam 42 hastadan elde edilen plazma örnekleri dahil edilmiş ve her iki test sistemi ile de HCV-RNA düzeyi araştırılmıştır. Örneklerin 13 (%30.9)'ünde her iki test ile de negatif, 26 (%61.9)'sın-da ise her iki test ile de pozitif sonuç elde edilmiştir. İki örnekte VERSANT sistemi ile sırasıyla 3.38 ve 3.41 log10 lU/ml HCV-RNA tespit edilirken, COBAS ile negatif sonuç alınmış; bir örnekte ise COBAS ile viral yük 2.52 log10 lU/ml olarak belirlenirken, VERSANT sistemi ile negatif sonuç elde edilmiştir. Pearson korelasyon analizi ile her iki testin korelasyonunun ve linearitesinin yüksek [(r= 0.904, p< 0.0005), (R2= 0.817)] olduğu belirlenmiştir. COBAS AmpliPrep/COBAS Taqman 48 ile belirlenen viral yük değerlerinin, VERSANT HCV-RNA 3.0 ile tespit edilen değerlerden ortalama 0.33 log10 lU/ml daha yüksek olduğu izlenmiştir. Sonuç olarak; HCV-RNA kantitasyonunda her iki sistemle de benzer sonuçlar alınabildiği saptanmış, ancak viral yük değerlerindeki farklılık nedeniyle tedavi takibinin her zaman aynı test sistemi ile yapılmasının uygun olacağı kanısına varılmıştır.
